This Mega‑Structure — It’s 10% of the Universe

[00:00:01]Astronomers found something in deep space so massive and so vast that it breaks the rules of the universe. It's called the Hercules Corona Borealis Great Wall, a colossal structure of galaxies stretching 10 billion light-years across. That's nearly 1/10 the size of the entire observable universe, a scale so huge it almost feels impossible to imagine. And here's [music] the truly impossible part.

[00:00:31]According to the laws of cosmic expansion, [music] nothing this large should ever be able to form. The universe simply isn't old [music] enough for gravity to pull something this enormous together. But there it is, a cosmic wall made of thousands of galaxy [music] clusters linked like a chain across unimaginable distances. Some scientists think it's [music] not a single structure at all, just a lucky alignment of galaxies along our line of sight. Others believe it's evidence [music] that the early universe was far more connected, structured, and mysterious than we ever imagined. A structure so big it [music] shouldn't exist, and yet it does.
